Secure management of accounts on display devices using a contactless card

ABSTRACT

Systems, methods, apparatuses, and computer-readable media for secure management of accounts on display devices using a contactless card. An application executing on a display device may receive a request specifying a service provider. The display device may receive a cryptogram generated a contactless card, and transmit the cryptogram to an authentication server. The authentication server may decrypt the cryptogram and generate a virtual account number associated with the contactless card. The authentication server may transmit the virtual account number to the service provider, which may create an account based at least in part on the virtual account number and the decryption of the cryptogram by the authentication server. The display may receive an authentication token generated by the service provider for the account, and access the account created by the service provider based at least in part on the authentication token.

BACKGROUND

Display devices, such as televisions, may provide different applications that allow users to access content hosted by service providers. Often, a user is required to pay for such services. However, most televisions do not have input interfaces that allow a user to easily enter their personal information. Furthermore, users of these input interfaces often make errors, requiring multiple attempts to enter correct information. These input interfaces may also pose security risks, as personal information may be visible on the display when entered by the user. Similarly, malicious users may be able to copy the input as the user enters the information via the input interfaces, thereby posing security risks.

SUMMARY

In one aspect, a method, includes receiving, by an application executing on a processor of a display device, a request includes a service provider, receiving, by a wireless card reader of the display device, a cryptogram generated by an applet of a contactless card, transmitting, by the application, the cryptogram to an authentication server associated with the contactless card, decrypting, by the authentication server, the cryptogram, generating, by the authentication server based on the decryption of the cryptogram, a virtual account number associated with the contactless card, transmitting, by the authentication server, the virtual account number to the service provider, creating, by the service provider, an account based at least in part on the virtual account number and the decryption of the cryptogram by the authentication server, receiving, by the application, an authentication token generated by the service provider for the account, accessing, by the application, the account created by the service provider based at least in part on the authentication token, and displaying, by the application, one or more attributes of the account generated by the service provider based on the authentication token. Other embodiments are described and claimed.

DETAILED DESCRIPTION

Embodiments disclosed herein provide techniques to securely manage service provider accounts on a display device, such as a television, using a contactless card. Generally, the display device may have a wireless card reader, such as a near-field communications (NFC) reader, that allows the display device to wirelessly communicate with a contactless card. To create a new account for a first service provider (or extend an existing account), such as a video-on-demand (VOD) service provider, a user may tap their contactless card to the display device. In response, the display device may instruct an applet executing on the contactless card to generate a cryptogram. The wireless card reader of the display may read the cryptogram and transmit the cryptogram to an authentication server for processing. If the authentication server is able to decrypt the cryptogram, the authentication server may generate a virtual account number for the contactless card. In some embodiments, the virtual account number is restricted to use with the first service provider (e.g., the virtual account number may only be used for payments with the first service provider). The authentication server may then transmit the virtual account number (and other data) as part of a request to generate an account to the first service provider. The first service provider may then generate an account for the user using the virtual account number (and other data) specified in the request. The first service provider may then generate an account authentication token for the account (or identify an existing token for the account) and transmit the token to the display device. In some embodiments, the first service provider may transmit the account token to other devices, such as to a manufacturer server associated with a manufacturer of the display device. Once received, an application executing on the display device may use the account token to access the account with the first service provider. For example, the user may view content hosted by the first service provider, view account details of the account created by the first service provider, and the like.

Furthermore, in some embodiments, the contactless card may be used to improve the login process for a plurality of service provider accounts. For example, a user may purchase a new display device and/or reset the software on a display device. The user may tap the contactless card to the display device, which causes the contactless card to generate a cryptogram and transmit the cryptogram to the display device. The display device may then transmit the cryptogram to the authentication server, which may decrypt the cryptogram. The authentication server may then identify, in payment records associated with the contactless card, one or more payment records for one or more service providers. For example, the authentication server may determine, based on the payment records, that the contactless card was used to pay for a subscription to service provider A. Based on the decryption of the cryptogram and the payment records, the authentication server may generate an authentication request for service provider A. The request may include a token generated by the authentication server. The authentication server may transmit the request to service provider A. Service provider A may then generate an account token for the account (or identify an existing account token for the account) and transmit the account token to the display device. An application associated with service provider A on the display device may use the token to log in to the account with service provider A. The new display device may automatically log in to the account with service provider A. Using this technique, the new display device may automatically log into any other accounts with service providers the contactless card has been used to provide payment data.

Advantageously, embodiments disclosed herein provide secure techniques creating and managing accounts on a display device using a contactless card. By leveraging cryptograms generated by contactless cards, embodiments of the disclosure may securely verify the identity of the user requesting to perform an operation with minimal risk of fraudulent activity. Furthermore, new accounts can be securely generated using payment information (e.g., a virtual account number) that is not compromised by a user entering the payment information on the display device. Doing so improves the security of the contactless card and the associated account. Further still, by providing an automated login process, embodiments disclosed herein may allow the display device to securely access all service provider accounts of the user with a single tap of the contactless card.

With general reference to notations and nomenclature used herein, one or more portions of the detailed description which follows may be presented in terms of program procedures executed on a computer or network of computers. These procedural descriptions and representations are used by those skilled in the art to most effectively convey the substances of their work to others skilled in the art. A procedure is here, and generally, conceived to be a self-consistent sequence of operations leading to a desired result. These operations are those requiring physical manipulations of physical quantities. Usually, though not necessarily, these quantities take the form of electrical, magnetic, or optical signals capable of being stored, transferred, combined, compared, and otherwise manipulated. It proves convenient at times, principally for reasons of common usage, to refer to these signals as bits, values, elements, symbols, characters, terms, numbers, or the like. It should be noted, however, that all of these and similar terms are to be associated with the appropriate physical quantities and are merely convenient labels applied to those quantities.

Further, these manipulations are often referred to in terms, such as adding or comparing, which are commonly associated with mental operations performed by a human operator. However, no such capability of a human operator is necessary, or desirable in most cases, in any of the operations described herein that form part of one or more embodiments. Rather, these operations are machine operations. Useful machines for performing operations of various embodiments include digital computers as selectively activated or configured by a computer program stored within that is written in accordance with the teachings herein, and/or include apparatus specially constructed for the required purpose or a digital computer. Various embodiments also relate to apparatus or systems for performing these operations. These apparatuses may be specially constructed for the required purpose. The required structure for a variety of these machines will be apparent from the description given.

Reference is now made to the drawings, wherein like reference numerals are used to refer to like elements throughout. In the following description, for the purpose of explanation, numerous specific details are set forth in order to provide a thorough understanding thereof. It may be evident, however, that the novel embodiments can be practiced without these specific details. In other instances, well-known structures and devices are shown in block diagram form in order to facilitate a description thereof. The intention is to cover all modification, equivalents, and alternatives within the scope of the claims.

FIG. 1A depicts an exemplary computing architecture 100, also referred to as a system, consistent with disclosed embodiments. Although the computing architecture 100 shown in FIGS. 1A-1E has a limited number of elements in a certain topology, it may be appreciated that the computing architecture 100 may include more or less elements in alternate topologies as desired for a given implementation. The system 100 comprises a display device 102, a contactless card 110, an authentication server 106, one or more manufacturer servers 138, one or more service provider servers 140, a memory 112, an applet 114, a counter 116, a master key 118, a diversified key 120, a customer ID 122, an application 126, a communications interface 128, a network 130, an authentication application 132, a memory 124, an account database 134, a cryptogram 136, an operating system 108, a memory 104, an account database 142, and an account database 144.

The contactless card 110 is representative of any type of card, such as a credit card, debit card, ATM card, gift card, smart card, and the like. The contactless card 110 may comprise one or more communications interfaces 128, such as a radio frequency identification (RFID) chip, configured to communicate with a communications interface 128 (also referred to herein as a “card reader”, a “wireless card reader”, and/or a “wireless communications interface”) of the display device 102 via NFC, the EMV standard, or other short-range protocols in wireless communication. Although NFC is used as an example communications protocol herein, the disclosure is equally applicable to other types of wireless communications, such as the EMV standard, Bluetooth, and/or Wi-Fi.

The display device 102 is representative of any number and type of display device, such as a television, monitor, projector, and the like. The authentication server 106, service provider server 140, and manufacturer server 138 are representative of any type of computing device, such as a server, workstation, compute cluster, cloud computing platform, virtualized computing system, and the like. Although not depicted for the sake of clarity, the display device 102, contactless card 110, and authentication server 106, service provider server 140, and manufacturer server 138 each include one or more processor circuits to execute programs, code, and/or instructions.

As shown, a memory 104 of the contactless card 110 includes an applet 114, a counter 116, a master key 118, a diversified key 120, and a unique customer ID 122. The applet 114 is executable code configured to perform the operations described herein. The counter 116, master key 118, diversified key 120, and customer ID 122 are used to provide security in the system 100 as described in greater detail below.

As shown, a memory 104 of the display device 102 includes an instance of an operating system (OS) 108, which may include an embedded operating system. Example operating systems 108 include webOS, Android® OS, iOS®, macOS®, Linux®, Tizen®, and Windows® operating systems. As shown, the operating system 108 includes one or more applications 126. The applications 126 are representative of any type of application, such as an application 126 provided by a service provider, a web browser, and the like. For example, a given application 126 may be associated with a service provider server 140. For example, an application 126-1 may be associated with a service provider server 140-1, and so on. Generally, a given application 126 allows users to access content items or other subscription-based services. For example, the applications 126 may be used to stream videos, audio, images, and any other type of content hosted by the service provider servers 140. However, because the service provider may require payment to access the associated services, the applications 126 may be used to view account details, register for services, make payments, update payment information, etc. The service providers may generally be any type of online service provider, such as video service providers, audio service providers, and the like.

As shown, a memory 124 of the authentication server 106 includes an authentication application 123. In some embodiments, to secure the contactless card 110, the application 126, and/or associated data, e.g., details of the user's account in the account database 134, account database 144, and/or account database 142, the system 100 may provide for secure account management using the contactless card 110. For example, a user may wish to open a new account with a service provider associated with service provider server 140, extend services for an existing account with the service provider, and the like. In some embodiments, the user may execute an application 126 associated with the service provider server 140, and may instruct the user to tap the contactless card 110 to the display device 102.

In the embodiment depicted in FIG. 1A, the user may tap the contactless card 110 to the display device 102 (or otherwise bring the contactless card 110 within communications range of the communications interface 128 of the display device 102). The applet 114 of the contactless card 110 may then generate a cryptogram 136. The cryptogram 136 may be based on the customer ID 122 of the contactless card 110. More generally, the cryptogram 136 may be generated based on any suitable cryptographic technique. In some embodiments, the applet 114 may include the cryptogram 136 and an unencrypted identifier (e.g., the customer ID 122, an identifier of the contactless card 110, an identifier of the application 126, and/or any other unique identifier) as part of a data package. In at least one embodiment, the data package is an NDEF file. In some embodiments, the application 126 transmits an application identifier to the applet 114, which may include the application identifier in the cryptogram 136 and/or unencrypted in the data package. The application identifier may uniquely identify a given application 126.

As stated, the computing architecture 100 is configured to implement key diversification to secure data, which may be referred to as a key diversification technique herein. Generally, the authentication server 106 (or another computing device) and the contactless card 110 may be provisioned with the same master key 118 (also referred to as a master symmetric key). More specifically, each contactless card 110 is programmed with a distinct master key 118 that has a corresponding pair in the authentication server 106. For example, when a contactless card 110 is manufactured, a unique master key 118 may be programmed into the memory 112 of the contactless card 110. Similarly, the unique master key 118 may be stored in a record of a customer associated with the contactless card 110 in the account database 134 of the authentication server 106 (and/or stored in a different secure location, such as hardware security module (HSM), not pictured). The master key 118 may be kept secret from all parties other than the contactless card 110 and authentication server 106, thereby enhancing security of the system 100. In some embodiments, the applet 114 of the contactless card 110 may encrypt and/or decrypt data (e.g., the customer ID 122) using the master key 118 and the data as input a cryptographic algorithm. For example, encrypting the customer ID 122 with the master key 118 may result in the cryptogram 136. Similarly, the authentication server 106 may encrypt and/or decrypt data associated with the contactless card 110 using the corresponding master key 118.

In other embodiments, the master keys 118 of the contactless card 110 and authentication server 106 may be used in conjunction with the counters 116 to enhance security using key diversification. The counters 116 comprise values that are synchronized between the contactless card 110 and authentication server 106. The counter 116 may comprise a number that changes each time data is exchanged between the contactless card 110 and the authentication server 106 (and/or the contactless card 110 and the display device 102). When preparing to send data (e.g., to the authentication server 106 and/or the display device 102), the applet 114 of the contactless card 110 may increment the counter 116. The applet 114 of the contactless card 110 may then provide the master key 118 and counter 116 as input to a cryptographic algorithm, which produces a diversified key 120 as output. The cryptographic algorithm may include encryption algorithms, hash-based message authentication code (HMAC) algorithms, cipher-based message authentication code (CMAC) algorithms, and the like. Non-limiting examples of the cryptographic algorithm may include a symmetric encryption algorithm such as 3DES or AES107; a symmetric HMAC algorithm, such as HMAC-SHA-256; and a symmetric CMAC algorithm such as AES-CMAC. Examples of key diversification techniques are described in greater detail in U.S. patent application Ser. No. 16/205,119, filed Nov. 29, 2018. The aforementioned patent application is incorporated by reference herein in its entirety.

Continuing with the key diversification example, the applet 114 may then encrypt the data (e.g., the customer ID 122 and/or any other data) using the diversified key 120 and the data as input to the cryptographic algorithm. For example, encrypting the customer ID 122 with the diversified key 120 may result in an encrypted customer ID (e.g., a cryptogram 136). The operating system 108 and/or the application 126 may then read the data package including the cryptogram 136 via the communications interface 128 of the display device 102.

The application 126 may then transmit the cryptogram 136 to the authentication server 106 with a request to generate an account with the service provider server 140. The request may be a generic request for any service offered by the service provider and/or a specific request for a specific service offered by the service provider. For example, the application 126 may allow the user to select one or more different service plans available with the service provider. The user may select one or more of the plans, and the application 126 may include an indication of the selected plan with the request. Further still, the application 126 may include another identifier, such as the unencrypted customer ID 122 provided by the applet 114 in the data package for the cryptogram 136. In some embodiments, the another identifier may be an identifier of the contactless card 110, an account identifier, an identifier of the application 126, and the like. Doing so may allow the authentication server 106 to identify the corresponding service provider server 140 when processing the request. Furthermore, in some embodiments, the application 126 may transmit additional data to the authentication server 106, such as location data for the display device 102. The location information may include global positioning system (GPS) coordinates, an IP address of the display device 102, and the like. Additionally and/or alternatively, the application 126 may include a unique identifier of the display device 102, such as a media access control (MAC) address of the display device 102 and/or another unique identifier.

FIG. 1B depicts an embodiment where the authentication server 106 attempts to decrypt the cryptogram 136. For example, the authentication application 132 may attempt to decrypt the cryptogram 136 using a copy of the master key 118 stored by the authentication server 106. In some embodiments, the authentication application 132 may identify the master key 118 and counter 116 using the unencrypted customer ID 122 (or other identifier) provided by the application 126 in the request. In some examples, the authentication application 132 may provide the master key 118 and counter 116 as input to the cryptographic algorithm, which produces a diversified key 120 as output. The resulting diversified key 120 may correspond to the diversified key 120 generated by the contactless card 110, which may be used to decrypt the cryptogram 136.

Regardless of the decryption technique used, the authentication application 132 may successfully decrypt the cryptogram 136, thereby verifying or authenticating the cryptogram 136 in the request (e.g., by comparing the customer ID 122 that is produced by decrypting the cryptogram 136 to a known customer ID stored in the account databases 134, and/or based on an indication that the decryption using the master key 118 and/or diversified key 120 was successful). The authentication application 132 may then transmit a decryption result 146 (also referred to as a “verification result” and/or an “authentication result”) to the display device 102. In some embodiments, the authentication application 132 may also transmit the decryption result 146 to the manufacturer server 138 and/or the service provider server 140. The decryption result 146 generally indicates whether the cryptogram 136 was decrypted and/or was not decrypted.

If the decryption is successful, the authentication application 132 may generate payment information comprising a virtual account number (VAN), expiration date of the VAN, and a card verification value (CVV) of the VAN. Furthermore, the authentication application 132 may identify metadata such as contact information for the user, e.g., an email address, phone number, etc., stored in the account database 134. The authentication application 126 may identify the metadata based on the unencrypted identifier included in the cryptogram 136. If the decryption is not successful, the authentication application 132 does not generate the payment information to preserve the security of the contactless card 110 and/or the associated account.

FIG. 1C depicts an embodiment where the decryption result 146 indicates the authentication application 132 successfully decrypted the cryptogram 136. Based on the successful decryption of the cryptogram 136, the authentication application 132 may generate payment information 148 comprising a virtual account number (VAN), expiration date of the VAN, and a card verification value (CVV) of the VAN. Furthermore, the authentication application 132 may identify contact information for the user, e.g., first name, last name, an email address, billing address, phone number, etc., stored in the account database 134. The authentication application 132 may identify the contact information based on the unencrypted identifier included in the cryptogram 136. The authentication application 132 may further include the contact information with the payment information 148. Further still, the authentication application 132 may include an identifier of the display device 102 and/or a service plan selected by the user with the payment information 148. More generally, the payment information payment information 148 may generally be included as part of a request to create an account (and/or extend services for an existing account) with the service provider server 140.

As shown, the authentication application 132 may transmit the payment information 148 (with expiration date, CVV, contact information, and identifier of the display device 102) to the manufacturer server 138 and/or the service provider server 140. In some embodiments, the payment information 148 is transmitted to the manufacturer server 138, which in turn transmits the payment information 148 to the service provider server 140. In some embodiments, the manufacturer server 138 and/or service provider server 140 may transmit a signal to the display device 102 to enable services with the service provider responsive to receiving the payment information 148.

In some embodiments, the authentication application 132 may leverage additional security measures before generating the payment information 148. For example, the authentication application 132 may generate a one-time passcode (OTP) and transmit the OTP to the identified contact information (e.g., to an email address, phone number, etc.). The user may then provide the OTP (e.g., alphanumeric characters) as input in an interface provided the authentication application 132, e.g., via a web browser and/or one of the applications 126. The authentication application 132 may compare the OTP received from the user to the generated OTP. If the comparison results in a match, the authentication application 132 may generate the payment information 148. If the comparison does not result in a match, the authentication application 132 may refrain from generating the payment information 148.

Additionally and/or alternatively, the authentication application 132 may analyze the location information (e.g., GPS coordinates, IP address) of the display device 102 as a security measure. For example, the authentication application 132 may determine a location of the display device 102 based on the GPS coordinates and/or the IP address of the display device 102. The authentication application 132 may then determine whether the determined location is within a predefined distance (e.g., 1 mile, 10 miles, etc.) of an address (e.g., mailing address, billing address) associated with the contactless card 110 in the account database 134. If the determined location of the display device 102 is within the predefined distance of the address associated with the contactless card 110, the authentication application 132 may generate the VAN. If the determined location of the display device 102 is not within the predefined distance of the address associated with the contactless card 110, the authentication application 132 may refrain from generating the payment information 148.

In some embodiments, the payment information 148, including the VAN, expiration date, and CVV, may be restricted to a merchant, e.g., the service provider corresponding to the service provider server 140. In such embodiments, the payment information 148 can only be used to process a payment with the merchant. If the payment information 148 is used as payment for a transaction with a different merchant (e.g., a different service provider, etc.), the authentication server 106 may reject the attempted transaction. For example, if the payment information 148 is restricted to service provider A, and the customer attempts to use the payment information 148 to pay for services with service provider B, the authentication server 106 may reject the attempted payment for service provider B.

FIG. 1D illustrates an embodiment where the service provider server 140 generates an account 150 in the account database 144 for the user based on the payment information 148 and any other information provided by the authentication server 106. For example, as stated, the authentication server 106 may include the user's email address, name, phone number, selected plan, etc. Similarly, the authentication server 106 may include an identifier of the display device 102, such as a device identifier, IP address, etc. The account record 150 may generally include this and any other information for the account 150. In some embodiments, the service provider server 140 may transmit a signal to the display device 102 to enable services with the service provider 140. In some embodiments, the signal is transmitted by the service provider server 140 to the manufacturer server 138, which then transmits the signal to the display device 102 to enable services with the service provider 140.

Furthermore, the service provider server 140 may generate an authentication token 152 for the account 150. The authentication token 152 may include any type of information, such as a hash value, to uniquely identify the authentication token 152. The authentication token 152 may further include additional attributes of the account 150, such as account numbers, preferences, login/password, etc. The service provider server 140 may transmit the authentication token 152 to the display device 102 and/or the manufacturer server 138. In some embodiments, the service provider server 140 transmits the authentication token 152 to the manufacturer server 138, which transmits the authentication token 152 to the display device 102. In some embodiments, the authentication token 152 is configured to enable access to services provided by the service provider server 140.

As shown, the application 126 of the display device 102 may receive the authentication token 152. In some embodiments, the application 126 may provide the authentication token 152 to the service provider server 140, which may authenticate the application 126 using the authentication token 152, e.g., based on comparing the authentication token 152 received from the display device 102 to the authentication token 152 stored in the account 150. If the comparison results in a match, the application 126 may be authenticated and the account 150 may be accessed, e.g., based on data/commands sent by the service provider server 140. Doing so may allow the user to view details of the account 150 on the display device 102 via the application 126, view content via the application 126, make purchases via the application 126, and the like. In some embodiments, the application 126 authenticates the authentication token 152 locally and accesses the account 150 based on locally stored data and/or data received from the service provider server 140.

FIG. 1E depicts an embodiment where the application 126, which has been authenticated with the service provider server 140 based on the authentication token 152, has requested a content item 154 from the service provider server 140. As shown, the service provider server 140 may transmit at least a portion of the content item 154 to the display device 102. The application 126 may display the received portion of the content item 154 on the display device 102.

FIG. 2A is a schematic 200 illustrating an embodiment of using the contactless card 110 to authenticate into a plurality of accounts with a plurality of service providers. Generally, users may subscribe to multiple services with multiple service providers. For example, a purchaser of a new display device 102 may have accounts with service providers X, Y, and Z. Advantageously, using the techniques described herein, the contactless card 110 may be used to log into the accounts with the service providers X, Y, and Z.

As shown, the user may tap the contactless card 110 to the display device 102, thereby causing the applet 114 to generate a cryptogram 136 as described above, e.g., by generating a diversified key 120 based on the master key 118 and counter 116, and generating the cryptogram 136 using the diversified key 120 to encrypt the customer ID 122. The cryptogram 136 may include the unencrypted customer ID 122. The display device 102 may transmit the cryptogram 136 to the authentication server 106, which may decrypt the cryptogram 136 as described above, e.g., by generating a diversified key 120 based on the master key 118 and counter 116, and decrypting the cryptogram 136 using the diversified key 120.

FIG. 2B illustrates an embodiment where the authentication server 106 decrypts the cryptogram 136 received in FIG. 2A. Based on the successful decryption, the authentication server 106 may search the account database 134 to identify payment records in the account associated with the contactless card 110. The search may be limited to known service providers. In some embodiments, the search is further limited to a recent time period (e.g., 1 month, 3 months, etc.). Doing so allows the authentication server 106 to identify any active accounts the user may have with the plurality of service providers. Continuing with the previous example, the authentication server 106 may identify payment records for service providers X, Y, and Z in the account database 134.

Based on the identified payment records, the authentication server 106 may generate an authentication token 202. The authentication token 202 may include contact information, account numbers with the service provider, a payment confirmation, or any information that may enable the service provider server 140 to identify an account in the account database 144. In some embodiments, the authentication server 106 generates a respective authentication token 202 for each identified account (e.g., a first authentication token 202 for service provider X, a second authentication token 202 for service provider Y, and a third authentication token 202 for service provider Z).

The authentication server 106 may transmit the authentication token 202 to the service provider server 140. In some embodiments, the authentication server 106 transmits the authentication token 202 to the manufacturer server 138, which may transmit the authentication token 202 to the service provider server 140. Generally, once received, the service provider server 140 may “trust” the authentication token 202 and generate an authentication token 202 that can be used to access the corresponding account via the application 126 of the display device 102. In some embodiments, rather than generating a new token, the service provider server 140 may use the authentication token 202 to provide access to the corresponding account in the account database 144.

FIG. 2C illustrates an embodiment where the service provider server 140 generates an authentication token 204 based on the authentication token 202 generated by the authentication server 106. While FIG. 2C illustrates a single instance of the authentication token 204, each service provider server 140 receiving an authentication token 202 may generate a respective authentication token 204. Continuing with the previous example, the service provider servers 140 for service providers X, Y, and Z may each generate a respective authentication token 204 (for a total of three authentication tokens 204). Once generated, the respective service provider server 140 transmits the authentication token 204 to the display device 102. In some embodiments, the service provider server 140 transmits the authentication token 204 to the manufacturer server 138, which in turn transmits the authentication token 204 to the display device 102. Each corresponding application 126 may receive the authentication token 204, which may be used to access the corresponding account in the account databases 144. Advantageously, doing so automatically logs the display device 102 into each service provider account based on the payment records in the account database 134 and the successful decryption of the cryptogram 136.

FIG. 3A is a schematic 300 a illustrating an embodiment where a contactless card 110 is tapped to a display device 102. As shown, the display device 102 may be executing an application 126 when the contactless card 110 is tapped to the display device 102. The communications interface 128 of the display device 102 may read a cryptogram generated by the applet 114 of the contactless card 110. The cryptogram may correspond to the cryptogram 136 described elsewhere herein. The application 126 may then transmit the cryptogram and any other data as part of a request to the authentication server 106. The additional data may include the unencrypted customer ID 122, an identifier of the display device 102, an identifier of the application 126, location information for the display device 102, and the like.

FIG. 3B is a schematic 300 b illustrating an embodiment where an account is automatically generated responsive to the request in FIG. 3A. Generally, in FIG. 3B, the authentication server 106 has verified (or authenticated) the cryptogram generated by the contactless card 110. Based on the verification (and any other additional security measures, such as location verification, OTP verification, etc.), the authentication server 106 may generate payment information comprising a VAN, expiration date, and CVV. The authentication server 106 may then transmit the payment information to the service provider server 140 associated with the requested service. In at least one embodiment, the authentication server 106 identifies the service provider server 140 based on the application 126 transmitting the cryptogram and/or an application identifier specified in the request transmitted by the application 126. The service provider server 140 may then generate an account record in the account database 144, and an authentication token for the account. The service provider server 140 may transmit the token to the requesting application 126 on the display device 102, which may then access the newly generated account based on the token. For example, as shown in FIG. 3B, the application 126 may display one or more attributes of the newly created account.

FIG. 4A is a schematic 400 a illustrating an embodiment where a contactless card 110 is tapped to a display device 102 to automatically log in to a plurality of service provider accounts using the contactless card 110. Generally, the display device 102 may be displaying a home screen of the operating system 108 and/or an application 126 when the contactless card 110 is tapped to the display device 102. The communications interface 128 of the display device 102 may read a cryptogram generated by the applet 114 of the contactless card 110. The cryptogram may correspond to the cryptogram 136 described elsewhere herein. The application 126 may then transmit the cryptogram and any other data as part of a request to the authentication server 106. The additional data may include the unencrypted customer ID 122, an identifier of the display device 102, an identifier of the application 126, location information for the display device 102, and the like.

FIG. 4B is a schematic 400 b illustrating an embodiment where the display device 102 is logged into example accounts with service providers A, B, and C based on the tap of the contactless card 110 to the display device 102 in FIG. 4A. Generally, the authentication server 106 may decrypt the cryptogram generated in FIG. 4A by the contactless card 110, thereby verifying the cryptogram. In response to the decryption, the authentication server 106 may identify one or more payment records in the account database 134. The payment records may include payments for one or more accounts with one or more service providers. For example, the authentication server 106 may identify payment records for service provider A, service provider B, and service provider C. The authentication server 106 may then generate an authentication token 202 for the account associated with the contactless card 110. The authentication server 106 may then transmit the token to each identified service provider server 140 based on the service providers identified in the payment records, e.g., the service provider servers 140 for service providers A, B, and C. The service provider servers 140 may identify an account in the account database 144 based on the received token. For example, the token may include a respective account number for the accounts in the account databases 144. Based on receiving the authentication token 202, the service provider servers 140 may generate a respective authentication token 202 for the identified account in the account database 144. The service provider servers 140 may then transmit the generated tokens to the display device 102, which may use the tokens to log into the accounts with service providers A, B, and C.

FIG. 7A illustrates an example configuration of a contactless card 110, which may include a contactless card, a payment card, such as a credit card, debit card, or gift card, issued by a service provider as displayed as service provider indicia 702 on the front or back of the contactless card 110. In some examples, the contactless card 110 is not related to a payment card, and may include, without limitation, an identification card. In some examples, the transaction card may include a dual interface contactless payment card, a rewards card, and so forth. The contactless card 110 may include a substrate 708, which may include a single layer or one or more laminated layers composed of plastics, metals, and other materials. Exemplary substrate materials include polyvinyl chloride, polyvinyl chloride acetate, acrylonitrile butadiene styrene, polycarbonate, polyesters, anodized titanium, palladium, gold, carbon, paper, and biodegradable materials. In some examples, the contactless card 110 may have physical characteristics compliant with the ID-1 format of the ISO/IEC 7816 standard, and the transaction card may otherwise be compliant with the ISO/IEC 14443 standard. However, it is understood that the contactless card 110 according to the present disclosure may have different characteristics, and the present disclosure does not require a transaction card to be implemented in a payment card.

The contactless card 110 may also include identification information 706 displayed on the front and/or back of the card, and a contact pad 704. The contact pad 704 may include one or more pads and be configured to establish contact with another client device, such as an ATM, a user device, smartphone, laptop, desktop, or tablet computer via transaction cards. The contact pad may be designed in accordance with one or more standards, such as ISO/IEC 7816 standard, and enable communication in accordance with the EMV protocol. The contactless card 110 may also include processing circuitry, antenna and other components as will be further discussed in FIG. 7B. These components may be located behind the contact pad 704 or elsewhere on the substrate 708, e.g. within a different layer of the substrate 708, and may electrically and physically coupled with the contact pad 704. The contactless card 110 may also include a magnetic strip or tape, which may be located on the back of the card (not shown in FIG. 7A). The contactless card 110 may also include a Near-Field Communication (NFC) device coupled with an antenna capable of communicating via the NFC protocol. Embodiments are not limited in this manner.

As illustrated in FIG. 7B, the contact pad 704 of contactless card 110 may include processing circuitry 716 for storing, processing, and communicating information, including a processor 710, a memory 712, and one or more communications interface 128. It is understood that the processing circuitry 716 may contain additional components, including processors, memories, error and parity/CRC checkers, data encoders, anticollision algorithms, controllers, command decoders, security primitives and tamperproofing hardware, as necessary to perform the functions described herein.

The memory 712 may be a read-only memory, write-once read-multiple memory or read/write memory, e.g., RAM, ROM, and EEPROM, and the contactless card 110 may include one or more of these memories. A read-only memory may be factory programmable as read-only or one-time programmable. One-time programmability provides the opportunity to write once then read many times. A write once/read-multiple memory may be programmed at a point in time after the memory chip has left the factory. Once the memory is programmed, it may not be rewritten, but it may be read many times. A read/write memory may be programmed and re-programed many times after leaving the factory. A read/write memory may also be read many times after leaving the factory. In some instances, the memory 712 may be encrypted memory utilizing an encryption algorithm executed by the processor 710 to encrypted data.

The memory 712 may be configured to store one or more applet 114, one or more counter 116, a customer ID 122, and the account number(s) 714, which may be virtual account numbers. The one or more applet 114 may comprise one or more software applications configured to execute on one or more contactless cards, such as a Java® Card applet. However, it is understood that applet 114 are not limited to Java Card applets, and instead may be any software application operable on contactless cards or other devices having limited memory. The one or more counter 116 may comprise a numeric counter sufficient to store an integer. The customer ID 122 may comprise a unique alphanumeric identifier assigned to a user of the contactless card 110, and the identifier may distinguish the user of the contactless card from other contactless card users. In some examples, the customer ID 122 may identify both a customer and an account assigned to that customer and may further identify the contactless card 110 associated with the customer's account. As stated, the account number(s) 714 may include thousands of one-time use virtual account numbers associated with the contactless card 110. An applet 114 of the contactless card 110 may be configured to manage the account number(s) 714 (e.g., to select an account number(s) 714, mark the selected account number(s) 714 as used, and transmit the account number(s) 714 to a mobile device for autofilling by an autofilling service.

The processor 710 and memory elements of the foregoing exemplary embodiments are described with reference to the contact pad 704, but the present disclosure is not limited thereto. It is understood that these elements may be implemented outside of the contact pad 704 or entirely separate from it, or as further elements in addition to processor 710 and memory 712 elements located within the contact pad 704.

In some examples, the contactless card 110 may comprise one or more antenna(s) 718. The one or more antenna(s) 718 may be placed within the contactless card 110 and around the processing circuitry 716 of the contact pad 704. For example, the one or more antenna(s) 718 may be integral with the processing circuitry 716 and the one or more antenna(s) 718 may be used with an external booster coil. As another example, the one or more antenna(s) 718 may be external to the contact pad 704 and the processing circuitry 716.

In an embodiment, the coil of contactless card 110 may act as the secondary of an air core transformer. The terminal may communicate with the contactless card 110 by cutting power or amplitude modulation. The contactless card 110 may infer the data transmitted from the terminal using the gaps in the contactless card's power connection, which may be functionally maintained through one or more capacitors. The contactless card 110 may communicate back by switching a load on the contactless card's coil or load modulation. Load modulation may be detected in the terminal's coil through interference. More generally, using the antenna(s) 718, processor 710, and/or the memory 712, the contactless card 110 provides a communications interface to communicate via NFC, Bluetooth, and/or Wi-Fi communications.

As explained above, contactless card 110 may be built on a software platform operable on smart cards or other devices having limited memory, such as JavaCard, and one or more or more applications or applets may be securely executed. Applet 114 may be added to contactless cards to provide a one-time password (OTP) for multifactor authentication (MFA) in various mobile application-based use cases. Applet 114 may be configured to respond to one or more requests, such as near field data exchange requests, from a reader, such as a mobile NFC reader (e.g., of a mobile device or point-of-sale terminal), and produce an NDEF message that comprises a cryptographically secure OTP encoded as an NDEF text tag.

One example of an NDEF OTP is an NDEF short-record layout (SR=1). In such an example, one or more applet 114 may be configured to encode the OTP as an NDEF type 4 well known type text tag. In some examples, NDEF messages may comprise one or more records. The applet 114 may be configured to add one or more static tag records in addition to the OTP record.

In some examples, the one or more applet 114 may be configured to emulate an RFID tag. The RFID tag may include one or more polymorphic tags. In some examples, each time the tag is read, different cryptographic data is presented that may indicate the authenticity of the contactless card. Based on the one or more applet 114, an NFC read of the tag may be processed, the data may be transmitted to a server, such as a server of a banking system, and the data may be validated at the server.

In some examples, the contactless card 110 and server may include certain data such that the card may be properly identified. The contactless card 110 may include one or more unique identifiers (not pictured). Each time a read operation takes place, the counter 116 may be configured to increment. In some examples, each time data from the contactless card 110 is read (e.g., by a mobile device), the counter 116 is transmitted to the server for validation and determines whether the counter 116 are equal (as part of the validation) to a counter of the server.

The one or more counters 116 may be configured to prevent a replay attack. For example, if a cryptogram has been obtained and replayed, that cryptogram is immediately rejected if the counter 116 has been read or used or otherwise passed over. If the counter 116 has not been used, it may be replayed. In some examples, the counter that is incremented on the card is different from the counter that is incremented for transactions. The contactless card 110 is unable to determine the application transaction counter 116 since there is no communication between applet 114 on the contactless card 110. In some examples, the contactless card 110 may comprise a first applet 114-1, which may be a transaction applet, and a second applet 114-2. Each applet 114-1 and 114-2 may comprise a respective counter 116.

In some examples, the counter 116 may get out of sync. In some examples, to account for accidental reads that initiate transactions, such as reading at an angle, the counter 116 may increment but the application does not process the counter 116. In some examples, when the reading device (e.g., the display device 102) is woken up, NFC may be enabled and the device may be configured to read available tags, but no action is taken responsive to the reads.

To keep the counter 116 in sync, an application, such as a background application, may be executed that would be configured to detect when the a device such as the display device 102 wakes up and synchronize with the server of a banking system indicating that a read that occurred due to detection to then move the counter 116 forward. In other examples, Hashed One Time Password may be utilized such that a window of mis-synchronization may be accepted. For example, if within a threshold of 10, the counter 116 may be configured to move forward. But if within a different threshold number, for example within 10 or 1000, a request for performing re-synchronization may be processed which requests via one or more applications that the user tap, gesture, or otherwise indicate one or more times via the user's device. If the counter 116 increases in the appropriate sequence, then it possible to know that the user has done so.

The key diversification technique described herein with reference to the counter 116, master key 118, and diversified key 120, is one example of encryption and/or decryption a key diversification technique. This example key diversification technique should not be considered limiting of the disclosure, as the disclosure is equally applicable to other types of key diversification techniques.

During the creation process of the contactless card 110, two cryptographic keys may be assigned uniquely per card. The cryptographic keys may comprise symmetric keys which may be used in both encryption and decryption of data. Triple DES (3DES) algorithm may be used by EMV and it is implemented by hardware in the contactless card 110. By using the key diversification process, one or more keys may be derived from a master key based upon uniquely identifiable information for each entity that requires a key.

In some examples, to overcome deficiencies of 3DES algorithms, which may be susceptible to vulnerabilities, a session key may be derived (such as a unique key per session) but rather than using the master key, the unique card-derived keys and the counter may be used as diversification data. For example, each time the contactless card 110 is used in operation, a different key may be used for creating the message authentication code (MAC) and for performing the encryption. This results in a triple layer of cryptography. The session keys may be generated by the one or more applets and derived by using the application transaction counter with one or more algorithms (as defined in EMV 4.3 Book 2 A1.3.1 Common Session Key Derivation).

Further, the increment for each card may be unique, and assigned either by personalization, or algorithmically assigned by some identifying information. For example, odd numbered cards may increment by 2 and even numbered cards may increment by 5. In some examples, the increment may also vary in sequential reads, such that one card may increment in sequence by 1, 3, 5, 2, 2, . . . repeating. The specific sequence or algorithmic sequence may be defined at personalization time, or from one or more processes derived from unique identifiers. This can make it harder for a replay attacker to generalize from a small number of card instances.

The authentication message may be delivered as the content of a text NDEF record in hexadecimal ASCII format. In another example, the NDEF record may be encoded in hexadecimal format.

FIG. 8 is a timing diagram illustrating an example sequence for providing authenticated access according to one or more embodiments of the present disclosure. Sequence flow 800 may include contactless card 110 and display device 102, which may include an application 126 and processor 802.

At line 806, the application 126 communicates with the contactless card 110 (e.g., after being brought near the contactless card 110). Communication between the application 126 and the contactless card 110 may involve the contactless card 110 being sufficiently close to a card reader (not shown) of the display device 102 to enable NFC data transfer between the application 126 and the contactless card 110.

At line 804, after communication has been established between display device 102 and contactless card 110, contactless card 110 generates a message authentication code (MAC) cryptogram. In some examples, this may occur when the contactless card 110 is read by the application 126. In particular, this may occur upon a read, such as an NFC read, of a near field data exchange (NDEF) tag, which may be created in accordance with the NFC Data Exchange Format. For example, a reader application, such as application 126, may transmit a message, such as an applet select message, with the applet ID of an NDEF producing applet. Upon confirmation of the selection, a sequence of select file messages followed by read file messages may be transmitted. For example, the sequence may include “Select Capabilities file”, “Read Capabilities file”, and “Select NDEF file”. At this point, a counter value maintained by the contactless card 110 may be updated or incremented, which may be followed by “Read NDEF file.” At this point, the message may be generated which may include a header and a shared secret. Session keys may then be generated. The MAC cryptogram (e.g., the cryptogram 136) may be created from the message, which may include the header and the shared secret. The MAC cryptogram may then be concatenated with one or more blocks of random data, and the MAC cryptogram and a random number (RND) may be encrypted with the session key. Thereafter, the cryptogram and the header may be concatenated, and encoded as ASCII hex and returned in NDEF message format (responsive to the “Read NDEF file” message).

In some examples, the MAC cryptogram may be transmitted as an NDEF tag, and in other examples the MAC cryptogram may be included with a uniform resource indicator (e.g., as a formatted string). In some examples, application 126 may be configured to transmit a request to contactless card 110, the request comprising an instruction to generate a MAC cryptogram.

At line 808, the contactless card 110 sends the MAC cryptogram to the application 126. In some examples, the transmission of the MAC cryptogram occurs via NFC, however, the present disclosure is not limited thereto. In other examples, this communication may occur via Bluetooth, Wi-Fi, or other means of wireless data communication. At line 810, the application 126 communicates the MAC cryptogram to the processor 802.

At line 812, the processor 802 verifies the MAC cryptogram pursuant to an instruction from the application 126. For example, the MAC cryptogram may be verified, as explained below. In some examples, verifying the MAC cryptogram may be performed by a device other than display device 102, such as a server of a banking system in data communication with the display device 102. For example, processor 802 may output the MAC cryptogram for transmission to the server of the banking system, which may verify the MAC cryptogram. In some examples, the MAC cryptogram may function as a digital signature for purposes of verification. Other digital signature algorithms, such as public key asymmetric algorithms, e.g., the Digital Signature Algorithm and the RSA algorithm, or zero knowledge protocols, may be used to perform this verification.

FIG. 9 illustrates an NDEF short-record layout (SR=1) data structure 900 according to an example embodiment. One or more applets may be configured to encode the OTP as an NDEF type 4 well known type text tag. In some examples, NDEF messages may comprise one or more records. The applets may be configured to add one or more static tag records in addition to the OTP record. Exemplary tags include, without limitation, Tag type: well known type, text, encoding English (en); Applet ID: D2760000850101; Capabilities: read-only access; Encoding: the authentication message may be encoded as ASCII hex; type-length-value (TLV) data may be provided as a personalization parameter that may be used to generate the NDEF message.
